This invention relates to an improved glue applicator of the rotary disc type, the primary object of the invention being to provide a simpler, more efiicient, and more versatile device of this kind wherein two applicator discs are involved which can be adjusted axially with respect to each other in order to apply the glue to narrow and to wider work, together with adjustable guide means for guiding the work in contact with the discs.

Another important object of the invention is to provide a motor driven device of the character indicated above which, aside from the motor which is removable, is in the form of a unit which can be immersed in water when desired and not in use, without harm thereto.

Other important objects and advantageous features of the invention will be apparent from the following description and the accompanying drawings, wherein, for purposes of illustration only, a specific embodiment of the invention is set forth in detail.

In the drawings, wherein like numerals designate like parts throughout the several views:

Figure 1 is a top plan view;

Figure 2 is a vertical longitudinal section taken on the line 2--2 of Figure 4;

Figure 3 is a rear elevation; and

Figure 4 is a transverse vertical section taken on the line 4-4 of Figure 2. I

Referring in detail to the drawings, the illustrated glue applicator 5 is adapted for mounting upon a horizontal support 6, such as a work table, in association with a rectangular open top tank or container resting upon the support 6 and containing glue 8, to be applied to such as portions of furniture (not shown) in a furniture factory. Obviously, the applicator is not necessarily limited to applying glue, or to applying glue to furniture pieces but is adaptable to applying other fluids to selected objects.

The applicator 5 comprises a bracket or column 9 comprising a horizontal plate I forming a base or foot to rest upon the horizontal support 6, a vertical plate II rising from the base III, and a horizontal plate I2 on the upper end of the plate I I. The horizontal plate I2 includes a relatively small square portion I4 constituting a motor supporting platform, located over the column 9, and a relatively large longitudinally elongated work supporting or table portion I extending beyond opposite sides of and in front of the platform I4. The work supporting or table portion I5 has parallel longitudinal rear and front edges I6 and I1,

respectively, and is formed with a rectangular 5 Claims. (01. 11s-222) opening I8, elongated in the same direction as the table portion I5, and having rear and front edges I9 and 20, respectively, parallelly spaced from the edges I6 and H of the table portion l5, as shown in Figure 1, and end edges 2| parallelly spaced from and located outwardly of the sides of the platform I4. The parts 3, I4 and I5 constitute the frame of the device and are preferably made of rust resistant and non-corroding material like Babbitt metal.

A suitable ratioed electric motor 23 has a base 23' resting upon the platform I4 and removably secured thereto by suitable means indicated at 24, with its shaft 25 directed forwardly and provided on its forward end with a bevel pinion 26. I

The top of the portion 21 of the table portion I5 located immediately between the platform I4 and the rear edge [9 of the opening I8, serves as a supporting surface for the parallelly spaced, transversely elongated and rearwardly extending horizontal feet 28 of the work guide 29, the feet 28 projecting from the lower edge of a vertical, longitudinally elongated work guide plate 30, extending substantially parallel to the rear edge I9 of the opening I8. Studs 3I fixed to the portion 2'! rise through longitudinal slots 32 formed in the feet 28 and are provided with wing nuts 33 whereby the guide plate 30 can be secured in adjusted position. The guide 29, studs 3I, and wing nuts 33 are preferably of brass or of other rust and corrosion resisting metal.

At a point midway between the studs 3 I, a vertical, preferably brass, drive shaft 34 extends through the portion 21 and above and below the table portion I5 and is supportably journaled in a bearing 35 locatedl'below the portion 21 and secured to a forward extension 36 on the vertical bracket plate II, as shown in Figure 4. Preferably brass bevel pinions 31 and 38 are secured on the upper and lower ends, respectively, of the drive shaft 34, the upper pinion 31 being in mesh with the motor shaft pinion 26.

The table portion I5 has parallel rear and front ribs 40 and 4|, respectively, projecting on its underside and extending the length thereof, the rear rib 40 being located along the rear edge I3 of the opening I8, and the front rib 4| being located along the front edge 20 of the table portion I5. These ribs serve as stiffening reinforcements for the table portion I5 and can rest removably upon the upper edge 42 of the glue tank or container I where the tank or container I, when in position upon the horizontal support l6, is of sufiicient height. Spaced legs 43 depend from the front rib 41 to engage within the tank through and journaled in a bearing 45 in the lower part of the rear arm 44, having e, fixed bevel pinion 55 thereon in mesh with the pinion 38 on the lower end of the drive shaft 3 1. nrla -po's'iteside's of said opening'an'd depending therefrom, a transverse shaft journaled in and explaced in water or other cleaning fluid without risk of rusting or corroding the same.

What is claimed is:

1. In a fluid applicator, a vertical bracket having a lower end arranged to rest upon a support, a horizontal work-supporting plate mounted on and extending from one side of the bracket at a level above the lower end of the bracket, said plate being formed with a transverse opening, said horizontal jplate having verfiidaljarms at optending between lower portions of said arms, ap-

tively short rear sleeve 5! is circumposed on and secured to the spindle 3'? in front of "the arm 4% and has circumposed thereon the hub- 5 2 oi the;

rear applicator disc 53 whereby the rear disc 53 occupies a stationary, position near the rear-edge l9of the opening [-8 in the table'portion-w, as shown in Figure 4;. A- set screw'54 traversing the hub 52 locks the disc 53 in position in the short sleeve .53 permits some adjustment ,thereof along the sleeve 5-! 1 The driven shaft dt iurther comprises a -relativel-y -long front sleeve 55 which is threaded on the threaded front portion 56 of the spindle til,

so as to be adjustable alongthe spindle 4 iii-1,;

ei'ther direction. A look nut- 57 on the front end portion of the threaded spindle portion 56 is provided to be engaged with theirontend 58 of the long sleeve to lock the same in adjusted "position along the spindle Al. The front end .portion of the long sleeve 55 is journaled in and slidable-through the cover part of the front-arm -45, as indicated at 59. The front applicator disc FGiiis similar to the rear applicator disc 53 and has -a hub "55 circumposed on the rear end of the :long sleeve 55and secured thereon by a set screw 52. As-aconsequence, when the sleeve is adjusted along the spindle 4'1, the frcnt disc -50 is correspondingly adjusted toward or away from the rear-disc 53, asm-av be required to apiply =to differently space-d areas of .-a work piece The applicator discs 53 and Ebb-ave oppositely bevelled peripheral applicator surfaces 55 which .--pr oject through the opening 18 and above the table .por-tion l5, and plane smooth facing suriacesfifi which are engageable, "shownin Fi LlI'G-fl, in the extreme rearward adjustment of the frontdisc 55. The frontdisc Ellis adjustable, by the means described above, to occupy .a'position near the front edge- 25 of the opening. f8,

wherein the 'front disc '55 is in substantially -spaced..relation-to the rear disc 53, and the pe ripheral applicator edges or surfaces .are spaced L-to apply ,g lue tof rlatively -'widely spaced area of a workpiece. Thework pieces are-moved along ithetable portion H5 in contact'with the guide Ipl'ate=3B-of theguide ilt as-thev are engaged with one or 'looth'o'f the peripheral applicator edges 55 of the discs, thereby assuring accurate and uniforin' application of the glue.
